Using Guix System, the bootloader declaration doesn't currently seem to
support being installed to multiple drives:

Toggle snippet (8 lines)
(bootloader (bootloader-configuration
(bootloader grub-bootloader)
(target "/dev/sda")
(terminal-outputs '(console))))
--8<---------------cut here---------------end--------------->8---

I suggest to change it so that target can be passed a list like
(bootloader (bootloader-configuration
(bootloader grub-bootloader)
(target '("/dev/sda" "/dev/sdb"))
(terminal-outputs '(console))))
--8<---------------cut here---------------end--------------->8---

This is useful when trying to boot a degraded RAID array.

The following patches do exactly this (target becomes the plural
targets). I tested it on my system, disconnecting the first drive of my
RAID1 array, and could at least boot to GRUB fine (although full boot

Booting a VM using an image generated from the bare-bones.tmpl template
also worked fine.
